Question

I have a UIImageView object X that is contained in an TableView object A. I want to be able to touch X and remove it from object A and move it into object B (a UIView). Both Object A & B are inside of the SplitViewController.

 A        B
_____    _____
|   |    |   |
| X | -> |   |
|___|    |___|

Is this possible at all?

Answer 1

Yes, this is possible.

1. Create a draggable UIView. Apple provides some sample code for that: MoveMe

2. When dragging starts, move the UIView X to the first common superview (someSuperview) of viewA and viewB:

   [someSuperview addSubview:viewX];

3. Adjust the frame of viewX, so its absolute position will remain identical :

   [viewA convertRect:viewX.frame toView:someSuperview];

4. Wait for the user to perform dragging/moving.

5. After the touches end, add viewX to viewB and convert the frame again.
